About
I'm a software architect and principal engineer based in Athens. I've spent the last decade building SaaS products — owning the stack end to end, from database schema to deployment pipeline.
I care deeply about simplicity: systems that are fast to reason about, safe to change, and built to last. I'm currently exploring neural networks and deep learning on the side.
